Here is the deal. I have an '88 IROC with a 350TPI. When I purchased this car, the wiring was a mess. The previous owner hacked a ton of wires and most were not fused. I redid most of the wiring in the dash/console area and deleted all of his crap that I could. The only issue left was that his old alarm screwed up the power door locks and they didn't work.

Now...about a year and a half later...My gauge fuse blew. I replaced it thinking it may have been a bad fuse and everything worked great for a few days. Then it blew again. I read through all of the other posts about it on here and traced everything I could think of. There are no wires shorting that I can find, and the fuse is fine as long as I am idling or driving normally. If I put my foot down the fuse blows. I have tried to figure out exactly when it is blowing and I believe it is somewhere around when the tranny shifts from first to second.

I am lost on what to trace next. Does anyone have any ideas what could be causing this?
